Focus lenses are essential accessories for achieving maximum precision and efficiency with your Trotec laser system. By selecting the correct lens with the appropriate focal distance, you can optimize cutting accuracy, engraving detail, and energy efficiency across a wide range of materials and applications.

 

Much like using different lenses on a camera for close-up or wide-angle shots, laser focus lenses determine how the beam interacts with the material. The focal distance defines where the beam reaches its smallest diameter, directly impacting energy density and heat dispersion. Shorter focal lengths create finer detail with higher energy intensity, while longer focal lengths are ideal for cutting thicker materials. Choosing the right lens ensures professional, consistent results every time.

Additional Information

 

1.5 inch CO2 Graphics with fine detail, (resolution > 500 dpi), rubber stamps with thin letters
 		 Lower laser power, thin materials (e. g. paper), acrylic < 6 mm, wood of medium hardness < 8 mm.
2.0 inch CO2 Graphics with medium detail and resolution (resolution 500 dpi; with reduced definition up to a resolution of 100 dpi), standard engraving
 		 Medium laser power, acrylic < 8 mm, wood of medium hardness < 12 mm.
2.0 inch CO2 clearance lens Mainly used for cutting See 2.0 inch lens.
Increases the distance between laser head and material. Is especially useful if the increased distance is required due to the material and the graphic
2.5 inch CO2 Graphics with low detail, low resolution (< 500 dpi). Engraving on heat-sensitive materials (e. g. laminate) if large areas have to be removed completely. High laser power, acrylic <12 mm, wood of medium hardness <15 mm
Better quality of edges during laser cutting than for lower focal distances
2.5 inch CO2 clearance lens Mainly used for cutting.
 		 See 2.5 inch lens.
Increases the distance between laser head and material. Is especially useful if the increased distance is required due to the material and the graphic.
2.85 inch flexx

Standard lens for Speedy 300 flexx. Is transmissive for both CO2 lasers and fiber lasers. Both laser sources can be used without changing the lens.

 Characteristics as 2.5 inch CO2 lens or 3.2 inch fiber lens
3.2 inch fiber Standard lens for fiber lasers with extremely small focal diameter. Graphics with fine detail, ( > 500 dpi resolution)
 		  
3.75 inch CO2 Lens for SP500 rotary engraving unit. Permits engraving of round objects with diameters of less than 50 mm
 		  
4.0 inch CO2 Engraving by burning of wood, laser engraving of graphics with low detail with high laser powers
 		 Foam rubber
5.0 inch CO2 Is not used for laser engraving High laser power, acrylic < 25 mm, wood of medium hardness < 20 mm
Better quality of edges during laser cutting than for smaller focal distances
5.0 inch fiber Lens for fiber lasers if materials that are not absolutely plane are to be labeled. The greater focal distance results in a greater tolerance during focusing.  
7.5 inch CO2 (for SP1500) Is not used for laser engraving
 		 High laser power, acrylic < 40 mm,
Better quality of edges during laser cutting than for smaller focal distances
